Victory Nutrition Center

Like sandwiches, multivitamins pack several forms of nutrients into one bite, are safe for daily consumption, and often come in convenient packs of 100. Supplement sensibly with today's Groupon: for $20, you get $40 worth of vitamins and supplements at Victory Nutrition Center.

The packed shelves of Victory Nutrition Center's retail shop welcome physiques yearning for a boost with a sweeping selection of fitness supplements and vitamins. More than 100 sport-nutrition supplements from brands such as ALRI, Met-Rx, and CytoSport help muscles bulge smugly under fitted shirts and the paltry weight of jet liners. Hi-Tech Pharmaceuticals' multivitamins ($19.95 for 90 pills) fit 47 different vitamins, minerals, and herbs into a single daily tablet, and the company's Sleep-Rx ($39.95) dispels bedtime concerns with an all-natural formula that promotes relaxation. Customers pose supplement-based questions to helpful staff members roaming the store ready to explain why it's easier to get essential omega-3 fatty acids from Optimum Nutrition's fish-oil softgels ($13.99 for 100 pills) or cold-pressed flaxseed-oil softgels ($10.99 for 100 pills) than setting up a cardboard box propped on a stick to try to trap them.
